I like the idea of making an x pattern from plywood to support the panels. But I'm also wondering if 3/4" is thick enough to stay cool on the playa. I will PM Vinay to see what he thinks.

...all matter is merely energy condensed to a slow vibration – that we are all one consciousness experiencing itself subjectively. There's no such thing as death, life is only a dream, and we're the imagination of ourselves...

Vinay said that 3/4" panels should work particularly well for 6' stretch yurts, and maybe using a roof pole. I did however find a supplier close by that sells 1" @ $27 a pop. Seems kind of expensive. I'm wondering if I should try the 3/4" panels. We will be building an H12 to accommodate 3 people and storage.

I'm in n. nv and paid a little over $23 a sheet for 1". And I thought that was expensive, but worth it. You might just have a little bit better piece of mind if you can afford it and the 1" may hold up better after several uses .

Not an option for me. So I was thinking of getting the 3/4" thick stuff and glue them to some thin plywood (perhaps 1/4"?). I've been reading that plywood isn't the greatest material for the playa as it is heavy and a bitch to put up. But I can't seem to find anything other than 3/4" insulated panels in my area.

Any ideas?

I had the exact same problem. Saw someone else's solution and it worked out perfect. 3/4 + 1/2 taped together gives you a 1 1/4 panel. taped all edges with foil tape to join the panels.

Well that sounds like a good idea but the 3/4" panels here are $19 and not sure about the 1/2" ones, but I'm sure they are more than $8. Unless I can find a cheaper supplier...

I order my 2" panels through a building supply. They cater to contractors that use R-max/Thermax. On the surface, it sounds like a clusterfuck to glue panels. I haven't done it, but it sounds like something I could bugger up real fast... Try building supply and insulation companies. They deliver too.

The first year I went Hexayert I bought all 13, 1" for ~$350. Thought it was expensive at the time, but the second year came around and I only had to replace 1 panels. The third year came and I only had to replace 3 panels (3 because my tie downs tore them up during exodus). If your only using the panels for a week a year and keep them from getting wet they last a long time. I discovered water and people are the panel's worst enemy.

You should always have at least 1 extra, just in case one decides to break.

I've only recently been introduced to the hexayurt. What a fantastic design!! I REALLY want to build one for this (my first) burn.

I'm reading through the forum, but there's quite a lot of detailed info to wade through. Given that time is short I thought I'd ask directly because I don't want to miss order deadlines, and all that.

I live in Pasadena CA. Home Depot, Orchard, etc., don't seem to stock foil backed RMAX. Can somebody point me in the right direction... where do I buy the 1" foil backed boards? Also, is goodbuyguys the best place to buy tape, and how many rolls should I order?

Yes on goodbuyguys for tape. You are going to need enough to tape all the exposed edges, the ones you cut (for the roof) and the wall panels.

so a sheet is 8x4 = 24 ft for one wall board x6= 144 ft just for the walls. a roll of the tape is 60 yds (180 ft)

Then you've got the roof panels 8x4=24 x6=144 ft plus taping the diagonal cuts which are 10ft and you tape both cuts so 10ft x2=20x6=120 ft

walls 144 roof 144roof diag cuts 120 equals 408 ft this does not include taping any cut outs such as your door, windows, but that should be minimal

then you need tape for the playa when you put it together. 48 ft around the bottom and middle = 96 ft. Tape at each wall joint 4x6=24. Tape at each roof cut 12x10=120

You'll need 2 rolls on the playa (this will leave you some left over but you may need it)

so 3 rolls to construct and 2 rolls on the playa=5 rolls total. this will leave you with some extra but as it is getting close to the burn it would be better to have a little extra rather than not enough.

I've seen that people use aluminum tape for the edges. Is the necessary? I'd like to keep costs as low as possible. I'm thinking about 3" duct tape for the edges (prepared at home before leaving for the burn), and the bi-filament only to join the boards. Am I missing anything; is it essential to use alu tape for the edges?

jkisha, this doesn't say anything about being foil backed... that's what I've been searching for. Does that matter? Sorry if I'm being a dumb ass, just don't want to buy the wrong thing and cook my wife.

Thanks muchly

I live in Orange County and many of the home depots and lowes have the 1" RMAX panels. Just search around. The web sites for home depot and lowes will tell you if they have it in stock at whichever store. Search their site for Polyisocyanurate insulated sheathing. I did a quick search and the lowes in Burbank carries it. Home depot's are hit and miss, but lowes seems to have it at most stores. They might not understand what you are asking for when you go in. Just go find it. Make sure each panel is good and solid as many of them are all banged up.

BTW the foil tape at lowes isn't much more expensive than the gorilla duct tape. I'd suggest using the foil tape if you can. The bifil tape and the boards will cost a lot more than a few rolls of the foil tape, so its a minor expense. Better order the 6" bifil tape quick! I'm going to be building my yurt this week, the camp danger semi folding design. Hope all goes well!

So, you reckon it would be ok to use gorilla tape for the cut edges, and bi-fil to join the boards?

yes it would work. there is someone further back in this thread that used it and it seemed to be fine. I just use the bi-fil. I just went the "official" way with bi-fil. There's lots of different ways and variations now.

So, you reckon it would be ok to use gorilla tape for the cut edges, and bi-fil to join the boards?

The ONLY yurts I've hard of blowing apart and away in the wind where held together with duct tape. Either the tape simply didn't stick enough or the stickiness gave way in the heat.All duct tape is not equal. Some is stronger or holds better than others, or holds longer in the heat. Gorilla is known to be a stronger duct tape, like some of the "pro" duct tapes. Holds better? If we get a really hot year? A really windy year? YVMV.

Never heard of that happening when the recommended bi-filament is used. But that may be due to those choosing to use the recommended tape also follow all of the construction recommendations.

Thanks. I wasn't thinking about building the structure with duct tape. I was just asking if it was OK to edge the boards with duct tape. I know the structure's strength comes from the bi-fil, just wanted to avoid unnecessary costs associated with using bi-fil for everything. But, as has been pointed out to me, there isn't much saving to be gained from using duct or gorilla over alu tape for edging, so I think I'll stick with the standard format and use alu tape for the edging and bi-fil for the construction.

We did our test build today. Can't wait to live in it for ten days. Writing up a blog post with plenty of pictures... In the mean time here a my glamour shot taken while marking the roof boards for cutting...

Thanks for the heads up on duct tape... same for gorilla tape?

That's the right stuff.

The stuff without foil doesn't have the writing on it and it looks like styrofoam.

And don't forget to wash it with mild soap to remove the milling oil before you start taping.

We get 6" bidirectional filament tape for assembly and for making the preasembly hinges for the roof sections and wall sections and for the weather stripping of the door and door hinge. We also buy 2" bidirectional filament tape for other taping-- taping on the windows, and taping the floor to the walls. We use foil tape for pre-taping the edges and for repairing any dings in the foil of the panels.

Much relieved.Get the 3" foil tape. Much easier than trying to get the 2" to do the job.
